I looked up the Customer Satisfaction Program #N222360900 and it says only 213 Hummers should need parts changed for Extract Mode Upgrade. Also says there is a GDS2 relearn after parts installed with a SPS reprogramming of the Sequential multiple modules. This document came out July 1st.

Just getting the information out there as Ive seen a few post confused what all it entails. I haven’t had the chance to do one yet, but in my opinion sounds like if you don’t need the parts, an OTA update would probably enable this feature could eventually if its just a reflash of a module.

You need an SME tag added above your user name as you are a verified tech.
